One of mine is still this way. When he was in high school and was the star in a play about a mentally challenged teen afraid of water, his big brother's comment to that was "Wow - that's a stretch - NOT".
He doesn't have laundry facilities at his apartment, so he "borrows" from his father or me. My daughter in law won't let him wash his clothing at her house (and my son, her husband, works on air craft engines, so his are a mess) because of the smell.
He's 21. He has a girlfriend. He has a job. Not much I can do about it.
